Patent DE-3233590-A1 (DE)
Inventor: DANIELS ERWIN J
IPC: G02C11/00
Filed: 1982-09-10
Abstract: The invention is directed to an ophthalmic lens having a marking and a method of producing the same. The lens is suitable for spectacles and the like. The method includes applying a removable adhering substance to a region of the surface of the lens body so that the peripheral outline of the substance corresponds to the marking to be formed. Then, an anti-reflection coating is applied to the lens body and, at a time thereafter, the adhering substance and the portion of the coating covering the substance is removed thereby causing a recess to be formed in the coating having a peripheral outline defining the marking. The marking formed in this way is practically invisible to a person wearing spectacles equipped with the lens of the invention. On the other hand, the marking is clearly visible when viewed in reflected light.

Patent DE-3335727-A1 (DE)
Title: Lever for attaching a dérailleur/tensioning mechanism for a cycle gear-shift
Inventor: FUETTERER WERNER
IPC: B62M25/04
Filed: 1983-10-01
Abstract: The previously known attachment of a dérailleur mechanism is performed with a clip which blocks the entire fork exit end and thus does not permit the running wheel or the chain to be regulated. In addition, attachment to fork exit ends which are open towards the rear is not possible with this clip. With the lever which is attached to the hub axis and like a brake lever with a binding to the fork blade it is possible to use the entire fork exit end for regulating purposes. In addition, with this lever it is possible to attach a dérailleur/tensioning mechanism to any known fork exit end. The gear-shift mechanism attached under the attachment of the axle always maintains the same distance from the hub gearwheels despite the lever displacement. This lever is a great advantage in particular for the combination of the two cycle gear-shifts of hub gear-shift with reverse-pedalling brake and a dérailleur gear-shift (for example specialist publication "Radmarkt" (Wheel Market) 11/82, page 43, Bielefelder Verlagsanstalt) because the chain is subsequently adjusted and thus the dead travel of the tread crank can be kept small, which means less risk of accidents. However, with this type of attachment, even cyclists who have a cycle with rearwardly open exit ends can still have a dérailleur gear-shift or the gear-shift combination mentioned above.

Title: Circuit arrangement for exchanging switching signals between telephone switching systems interconnected as primary and secondary systems
Inventor: SCHOENE LOTHAR
IPC: H04Q3/62
Filed: 1984-05-18
Abstract: With the present patent application, it is proposed that the extension lines running between the telephone switching systems are of four-wire design, the incoming direction in each case being connected directly to the reception input of a modem and also leading to the switching matrix of the telephone switching system, and the outgoing direction being connectable as required via individually connectable switching points either to the transmission input of the modem or to the switching matrix. The four-wire design of the extension lines offers the advantage that no hybrid circuits causing attenuation need to be contained in the transmission path for the switching signal exchange, with the result that no range losses occur. Furthermore, switching signal exchange can be carried out in full-duplex traffic, with the result that switching signal exchange can be carried out even when large amounts of information are involved.

Title: Operating procedure for a heat pump
Inventor: BAUMGAERTNER MANFRED DR
IPC: G05D23/20
Filed: 1984-08-09
Abstract: The invention relates to an operating procedure for a heat pump plant, which alternatively takes on hot water preparation and space heating. In this case, the heat pump 1 is controlled in space heating mode as a function of the comparison of an actual temperature value Ti with a desired temperature value Ts dependent on the thermal requirement. Upon switchover from space heating to hot water preparation, the result of the comparison of the desired temperature value and actual temperature value before the switchover point is stored. If after switchover from hot water preparation to space heating the actual temperature value Ti is below the desired temperature value Ts, heat pump 1 remains switched on. If, after switchover from hot water preparation to space heating, the actual temperature value Ti is above the desired temperature value Ts, the heat pump 1 is controlled for a time interval  DELTA t as a function of the stored result of the comparison of the desired temperature value and the actual temperature value and is not controlled again as a function of the current result of the comparison of the desired temperature value and actual temperature value until after expiry of this time interval  DELTA t. <IMAGE>
